One way is to consult a copy of "The Periodic Table of the Elements". Great Q'n!
Mass no-the no of proton=no of neutron
The mass number of a neutron is 1, as it contains one unit of mass. The mass number of a proton is also 1, as it contains one unit of mass. In hydrogen, the nucleus usually consists of one proton, so the mass number of a proton in hydrogen is 1.
the neutral or no charge particle of an atom:it is located in the nucleus;has the same mass as the proton.
Bcoz mass no is no of proton + no of neutron
Of the common sub-atomic particles, both the proton and the neutron have mass numbers of 1.
If a proton would be 1, an electron would be 0.000544. An electron is 1,836 times lighter than a proton. A neutron would be 1.001 as a proton is 99.86% the mass of a neutron
A neutron has approximately the same mass as a proton. Electrons have much lower mass.
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
atomic number = number of proton in an element number of proton = number of electron mass number = number of proton + number of neutron therefore... atomic number = mass number - number of neutrons
The mass of a proton is equal to a neutron.
